Illuminating surgical device and control element

Abstract

Embodiments of claimed subject matter are directed to an illuminating surgical device comprising a single control element to control an array of illuminating elements and an array of louvers to direct light from the individual illuminating elements toward a surgical field.

What is claimed is: 
     
       1. A surgical retraction device, comprising:
 means for illuminating a surgical area; 
 means for controlling one or more louvers proximate to the means for illuminating the surgical area to control placement of the illuminated surgical area along a first axis and a second axis substantially perpendicular to one another; and 
 means for stepping, in discrete steps, the intensity of the illumination of the surgical area using a single control element to control electric current delivered to the means for illuminating the surgical area. 
 
     
     
       2. The surgical retraction device of  claim 1 , wherein the means for controlling placement of the illuminated surgical area along the first axis comprises a stepper motor to operate to modify the position of the one or more louvers responsive to the movement of the single control element. 
     
     
       3. The surgical retraction device of  claim 2 , wherein the stepper motor operates to adjust an angle of the one or more louvers of an array of louvers, with respect to a plane of a two-dimensional array of organic light-emitting diodes. 
     
     
       4. An illuminating surgical device, comprising:
 a two-dimensional array of illuminating elements to direct light toward a surgical field; and 
 a single control element, to control intensity of light from the two-dimensional array of illuminating elements responsive to pressing the single control element, and movable along a first axis to control at least one louver to control the direction of the light within the surgical field from the two-dimensional array of illuminating elements in a direction parallel to the first axis, wherein the single control element is coupled to one or more switches, closure of the one or more switches to supply a signal to one or more illuminating elements of the two-dimensional array of illuminating elements. 
 
     
     
       5. The illuminating surgical device of  claim 4 , wherein the single control element is movable along a second axis substantially perpendicular to the first axis to control the direction of the light from the two-dimensional array of illuminating elements in a direction parallel to the second axis. 
     
     
       6. The illuminating surgical device of  claim 4 , wherein the pressing of the single control element is followed by releasing the single control element. 
     
     
       7. The illuminating surgical device of  claim 4 , wherein the single control element is configured to incrementally change intensity of the light from the two-dimensional array of illuminating elements responsive to a corresponding number of presses of the single control element. 
     
     
       8. The illuminating surgical device of  claim 4 , wherein the single control element is configured to incrementally change intensity of the light from the two-dimensional array of illuminating elements responsive to pressing and holding the single control element in place. 
     
     
       9. The illuminating surgical device of  claim 4 , further comprising a circuit to extinguish the illuminating surgical device based, at least in part, on inactivity of the illuminating surgical device over a duration. 
     
     
       10. The illuminating surgical device of  claim 4 , wherein the two-dimensional array of illuminating elements comprise organic light-emitting diodes (OLEDs).
